Abstract

Recently, we have discovered a new class of amino acids salts containing different amino acids. In the present paper, we report crystal structures of three isostructural salts: l-argininium(+) sarcosine chloride (I), l-argininium(+) sarcosine bromide (II), and l-argininium(+) sarcosine iodide (III), formed by slow evaporation at room temperature from aqueous solutions containing stoichiometric ratios of components. The compounds crystallize in the polar space group P21 with two formula units in the asymmetric unit. The structures are stabilized due to N–H···O and N–H···X (X = Cl, Br, I) hydrogen bonds. Infrared spectra of all three crystals are shown and discussed.
